I have owned and flown a 1979 Cessna 414A for 14 months, accumulating 235 hours in all sorts of conditions. I bought it to replace a nice Cessna T310R, which I flew for about a year. The upgrade from the T310R came about because my family, including a dog, cannot all be wearing nosebags. The pressurized comfort of the 414A, which produces an 8000-foot cabin at 22,800 feet, cannot be overemphasized. It is the flying carpet my wife always wanted, including a potty! The winglet mod works; I typically get 215 to 218 knots at mid-weight at FL220, running 72 percent power.
